Advances in the treatment of schizophrenia

We review advances in the treatment of schizophrenia. We begin with an overview of antipsychotic drug development, focusing on the in vitro and in vivo binding profiles of clozapine and a new generation of D2:5HT antagonists. We then consider the main barriers to effective treatment: non-compliance (and side-effects) of medication, recurrent relapse, 'treatment resistance', negative symptoms and neurocognitive deficits. Within this framework, we review the mechanisms of action and clinical uses of the 'atypical' antipsychotic drugs. We also show how a variety of psychosocial interventions, particularly those that incorporate cognitive techniques, can be used in combination with pharmacotherapy to overcome the same clinical hurdles.
